This invention relates to lubricating oil would generate heat and cause excessive wearl on the bearing surfaces. Numerous means have been utilized to accomplish this result as for example, various types of covers or oil plugs, the most desirableof which is an oil valve of the shell type that can be inserted in the bearing and not project to any great extent beyond the outside surface of the bearing. This eliminates the possibility of the valve being accidentally knocked oif.

In valves of the above character, a shell with a passage therethrough is inserted in the aperture of the bearing.l A diaphragm is mounted within the shell and movable vertically therein to'close one end of said passage, said .diaphragm being provided with downwardly extending lateral projections that engage the inner wall of the shell thus 30 permitting movement of the diaphragm and projections parallel to the side walls. A

typical illustration of a device of this character is the one shown in United States Letters Patent No. 67 8,931. A compression spring retains the diaphragm in engagement with and hermetically seals the outer opening of the shell.

With this construction, when an oil can spout is inserted through the outer opening of the valve and the diaphragm is compressed, unless due care is exercised, the passage in the oil can spout will be obstructed by the diaphragm and thereby prevent the free flow of the lubricant from the oil can through the valve of the bearing.

The object of my present invention is to provide a simple and eificient valve for oilholes and the like that can be manufactured at a minimum cost; that is capable of hermetically sealing the outer oil aperture; and,

when it is desired to introduce lubricant through the valve, the sealing member will be so positioned as to allow a free and ample passage without obstructing the flow from the introducing member. l 1 l/Viththe above and other objects in view, my invention consists in a novel construction and arrangement of parts hereinafter described and moreY specifically pointed out in the appended claims. f 6o In the accompanying drawing I have shown my improved oil-valve Sufficient to. enable those skilled inthe art tounderstand the construction yand operation thereof.

vReferring to thedrawingk- Fig. l is a vertical section ofmy oil valve inserted in a portion of a bearing,` Y

Fig. 2 is a view corresponding to lFig- 1 but shows some of the parts ina diiferent position; *Y j Y. ,A Fig. 3 isa plan view of my oil valve ,"and,

F ig. 4L is an enlarged sectional view ofthe hinge portion4 of my oil valve. Y

In theiaccompanying drawing 10 is a portion of al bearing having an aperture 11 75 formed therein to receive the valve shell 12. Thek shell body 12 is cylindrical in cross-y section and provided with an end wall 13, said end wall having formed therein a central circular opening 14. The shell body 12 8'0 has formed thereinl a flange 15 having an internal annular recess 16. 1

The circular opening-14 is hermetically closed by a cup` shaped diaphragm 17, .see Fig.,1, which has `extending therefroman k arm 18 which terminatesin a T lshaped end 18a which forms the hinge pin for the diaphragm. The hinge pin end of thearm 18 engages in the annular recess land is re-V tained therein by` meansof the flange V15 90 being depressed at the points19 and 20 thereby forming a fulcrum for the diaphragm.

The shell body l2 is provided, at the open end thereof, withV an inwardly extendingy flange 12a that forms a bearing for one end 95 of thecompression Vspring 21. '.llher opposite end of said spr'ingjhas its bearing in the cup shaped diaphragm 17 and acts to normally retain the diaphragm in a closed position as shown at Fig. 1.

When the oil can spout 22 is inserted through the aperture 14, see Fig. 2, the spring 21 is compressed by the diaphragm 17 Which swings on its pivot 18a. It Will be observed v that should the spout 22 be inserted in a vertical position'the diaphragm 17 Would be de- A lected onv an anglel thereby eliminating the possibilityrof obstructing the passage in the spout 22 throughwliioh the lubricant passes through the valve to the bearing.

Having thus des'cribedmy invention it"ir will be evident to those skilled in theart that Certain changes and modiications mayy be made therein by those skilled -in the -art Without departing from the spirit and scope y thereof, therefore, I do not Wish to be limited 'tof the VAspecific details hereindisclosed `butwhat I-claim is I 1.' An oil valve comprising a she-ll 0r case having a lateral, horizontally extending, substantially Ue-shaped annular flange formed integral therewith, a passage throughfsaid shell or case,la member, pivotally secured l Within said fUeshapedlange, by Which said passage is closed, means :tor retaining said member and passage a normally closed 1"Positionf f1 2.-An oil-valve comprising a shell orcase having a substantially closed-endwith a central opening therethrough, 'a horizontally eX- f 'tending U-shaped annular harige formed in tegral With said closed end and said shell, a member, pivotally secured Within said U shaped flange, by which said central opening is closed, means for retainingsaid member andopeningina normally closed position.

3. An oil valve comprising a-shell or case having a substantially closed end with acentral opening therethrough, a substantially U-shaped i annular flange formed integral with said closed end and said shell, a memf Y'ber engaging said centrall opening, said membei` having asubstantially T-shaped portion formed integral therewith and pivotally supported in said annular flange, means for normally retaining said-member in engagement Withesaid opening. v i

4. An oil valve comprising a cylindrical shell having a substantiallyclosed end with va centralopening therethrough, a substantially U-shaped flange disposedbetween said closed end andthe cylindrical shell, said flange having pivotally supported therein a 'pivotal extension of a cup-shaped member, said cup-shaped member engaging said cenv 'tralopening, means for ynormally retaining said cup-shaped member in engagement with said opening.

In testimony whereofl have hereunto set fmy hand.
